SHAFT-COUPLING;

Specification of Letters Patent.-' Patented Sept, 8, 1914,

Application filed May'21, 1913. Serial No. 768,934,

i To all whom it may concern:

Be it known that I, RorusR. HANSON, a

citizen of the UnitedStates, residing atBoston, county of Suflolk, andState of Massachusetts, have invented ful Improvements inShaft-Gouplings, of which the following is aspecification.

My invention relates to shaft couplings and particularly-to a couplingforconnecting the engine and magneto shafts in mo.'.

tor vehicles.

The object of my invention is to provide a coupling for the engine andmagneto shafts which may be readily adjusted to. properly time thespark.

A further object of my invention is to provide a device of theclass'mentioned, which shall be of simple construction, which may bereadily applied to the shafts and which will not readily get outoforder. Other objects will appear hereinafter. With these objects inView my invention consists generally in a clutch member fixed to one ofthe shafts, a clutch member in swiveled connection with the other shaftand means fixed to the same shaft for holding the swiveled clutch memberin adjusted position.

- My invent-ion further consists in various details 'of construction andarrangements of arts all as will be fully described hereinafter andparticularly pointed out in the claims. p

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in which-Figure 1 is an elevation of a clutch embodying my invention in itspreferred form,

Fig 2 1s a longitudinal section of the portion of the device attached tothe magneto shaft, Fig. 3 is an end elevation of the same; Fig. 4 is alongitudinal section of the portion. of the device on the engine shaft,Fig. 5 is an end view of the same and Fig. 6 is a sectional view takenon the line 00-00 of Fig. 2. V

Referring now to the drawings 1 indicates the engine shaft and 2 the'shaft of the magneto. Fixed to clutch member comprising a. sleeve 3 anddisk 4 upon the face of the latter of which is formed a plurality ofradially disposed ribs or bosses 5 to engage the clutch member on themagneto shaft. The clutch member is secured to the shaft -1 by a cotterpin 6.

certain. new and useupon the y the shaft 1- is a Fixed tothe magnetoshaft 2 is a sleeve 7', the bore at one end of which fits snugly thereduced portion 2 ofthe shaft 2 and the remainder of the bore beingoflarger diameter to receive the washer 8- and nut 9.

.10 indicates a key locking the sleeve against rotation on the shaft;The end of' the sleeve 7 is formed with an outwardly annular flange 11.Swiveled sleeve 7 and retained in position the flange 11 is a ring 12having an annular flange 13 projecting beyond the flange 11 and providedwith recesses 14 to receive the ribs or bosses 5 on the clutchmemberfixed to the engine shaft.

projecting Slidably mounted upon the sleeve 7 is an annular member 15formed with a pair of keys 16 arranged inlongitudinally disposed keyways 17 formed in the said sleeve. The annular member 15 is providedwith an annular series of apertures 18 to receive pins 19 projectingfrom the innerface of the ring 12. It is obvious that when thepins 19are engaged in the apertures 18, the clutch ring 12 is rotatably fixedto the shaft.

20 indicates a jamb nut threaded upon the V sleeve 7 to hold the annularmember 15 in engagement with the ring 12.

To setthe clutch in 'order to time the spark, the nut 20 is retractedand the annular member or ring 15 moved to disengage the pins 19 fromthe apertures 18. The ring 12 may then be turned until in properposition and theannular member 12 again movedi-nto engagement therewith,there beinga large number of apertures 18 and fine adjustment may bereadily obtained. The nut 20 is then screwed firmly against the member15 after which the device is ready for operation. Havlng described myinvention, I claim:

1. In a device of the class described, the adjacent shaft ends incombination with a clutch member fixed to one of said shafts, a sleevefixed to the other shaft, a clutch ring swiveled upon said sleeve, anannular member feathered upon said sleeve, cooperating means on saidswiveled clutch member and said annular member for locking the former inadjusted position, and means for holding said annular member inoperative position,

substantially as described.

2. In adevice of the class described, the adjacent shaft ends, a clutchmember fixed to one of said shafts, a clutch member rotatably mountedupon the other shaft, a

projection on the inner face of said last mentioned clutch member, asliding member carried by said last mentioned shaft, and rotatabletherewith, said member being provided with an annular series ofapertures adapted to receive said projection and means for holding saidmember in operative position, substantially as described.

Y 8. In a device of the class described, the adjacent shaft ends incombination with a' clutch member fixed to one of said shafts, anexternally threaded sleeve fixed to the other shaft, and provided on itsouter face' With a key Way, a clutch member swiveled upon the end ofsaid sleeve, an annular member slidably mounted on said sleeve andprovided with a key arranged in said ke Way, said annular member beingprovided With an annular series of apertures, a pin on the adjacent faceof saidswiveled clutch member adapted to engage in any ofsaid aperturesand a jamb nut threaded upon said sleeve and adapted to hold saidannular member in operative position, substantially as described. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
